Overview

Simple-to-use face recognition library with a focus on:

• Basic use - make a detector instance, then detect and recognize faces in one call.
• Well-known models - YuNet and ArcFace, both MIT-licensed upstream for peace of mind
• Small dependency footprint - Microsoft.ML.OnnxRuntime and SFML.NET graphics
• Friendly licensing - MIT for the code and upstream models, SFML.NET to avoid any concerns with commercial graphics licensing

How to Use

using var faceRecognizer = FaceRecognizer.Create(); var faces = faceRecognizer.DetectAndRecognize("your.jpg"); //List of faces with embeddings FaceRecognizer.Annotate(faces, "your.jpg", "your_annotated.jpg");

Use ONNX session options on the .Create() call to bring your own acceleration.
